I am interested in a gas golf cart frame and motor for a project I want to build. If found this Harley Davidson cart. The owner says he had the motor rebuilt $600.00 and it ran fine for a while but now he has a hard time keeping it running and the only way it will run is with the choke full on. Not sure what was included in the rebuild. I have no idea if you can still get HD parts. Any idea what to look for as far as the choke thing. Maybe it has a Tecumseh carb on it  :rolling:  Here is a picture of it.

my guess would be a crapped up carb or the electric inline fuel pump

I just noticed the old style fuel filter on the inlet to the fuel pump and the kinked fuel line going it to it. I would start there. that giant gas tank is probably full of stale water logged ethanol too

I used to have one of those.  Mine was a 1980.  When I got it the governor was disconnected and it went like a bat out of hell.  I put the governor back on after the daughters rolled it.

 

I'd agree that your problem is carb/fuel system.  If you have the same carburetor I had it has an integral vacuum operated fuel pump - the thing is similar to a chain saw or weed whip.  That aftermarket electric pump raises all sorts of red flags.  The carburetor needs to be set up properly, order a rebuild kit and the service manual from the link in the next paragraph.

 

Parts are readily available for the engine/carburetor.  This guy has most everything: http://www.golfcartcare.com/.  I got a piston and rings from him when I rebuilt the top end and various other parts from time to time.

 

I had trouble with it being hard to start after sitting - the fuel line would drain back into the tank.  Turns out there is supposed to be a check valve in the tank on the fuel pick up.  It was a commodity item I ordered through my local small engine shop.

Two stroke, right? If the seals on the main bearings go, it'll start like that too.

Looks a lot like the engine in my EZ Go golf cart.........2 stroke that runs in both directions, no transmission. 

 

I agree, its likely just the carb plugged up.

I'd do a compression test, I helped a friend with one of those and it took rings to get enough pulse to run the carb right. the problem with running a golf cart like a go cart is the cooling air intake plugs in about 5 min.s and the rest of the day the kids drive it over heating, or every day if not cleaned constantly. I showed this to my friend and told him if he didn't keep it clean he could expect more of the same,he never had another problem with it and sold it after 11yr.s when his kids graduated. they are tuff golf carts and this is the only draw back to driving them in the semi-rough.if you find nothing wrong in the fuel system this could be the problem. penny penny

Just had one of those here to work on.That one is made by EZ-Go Should have the same Tillotson carb with Fuel pump.It might still have the Fuel pump plate and valves on the carb.I would advise you to remove it if your using an electric pump.

 

Here is what the carb looks like with the pump removed and just the Float diaphragm and plate installed.They used these carbs on alot of older Snowmobile engines to so parts are very asy to find if you just want to rebuild the original diaphragm pump.

Wow!  I probably paid that much for repair parts.

I have a Yamaha that's still in operation.
Had carb, CDI, and ring issues. It was a mess of little problems.

Here is a pic of the original rings and one new one I broke during installation.
It was a hard starter. Wanted choke like crazy... Had like 2 for compression.

Now we're talking more my speed since I work on golf cars for a living. Out here, those machines are a dime a dozen, non running $100-200 for it typically.

 

I have two left that were trade ins if you need any parts.

Two stroke, right? If the seals on the main bearings go, it'll start like that too.

And it is usually the Clutch side of the crank..  If it sucks air the thing would lean out and burn the piston down in short order if ran hard.  What do the plugs look like?

Thanks for all the help. I don't own this yet as I found it on craigslist and wanted to know what I needed to do before I bought it. I sent the owner a list of questions but he never responded. If he doesn't want to answer calls he should take it off the site. I found another one that the owner says needs new seals in it. Not sure if that is all that it needs.
